(8) The mood is fantastic: upbeat, from a crowd of older locals reliving their youth to cool young thangs attracted by Margate’s burgeoning reputation as Dalston-sur-Mer; fiftysomething men in braces and Harringtons, candy-floss-chomping teens… People are picnicking on the fake lawn beside the hair and beauty caravan, children gyrating newly bought hula-hoops to the strains of I’ve Got a Lovely Bunch of Coconuts.
(9) The results of the synchrotron small-angle X-ray scattering measurements showed that radii of gyration which reflect the size and shape of the enzyme were constant at around 38 A irrespective of the presence or absence of the K+ ion.
(10) A viscosity study of the PEGs showed them to be randomly coiled polymers, as their radii of gyration were related to the molecular weight by Rg = aM0.55.
